For those arriving at Calcata Vecchia and wanting to descend into the Treja Valley, I strongly advise against taking the marked path that is not on the road: it is a pedestrian descent that can only be done with a bike in hand, and not even easily. Descend following the main asphalt road.

The Porta Romana in Campagnano di Roma is one of the historic entrances to the medieval village and a symbol of its identity. Impressive and well-preserved, it welcomes visitors with its stone structure that immediately evokes the atmosphere of the past. Crossing it means entering a town rich in history, with charming alleys and characteristic views. Today, it is also a landmark for pilgrims and travelers along the Via Francigena, who find here one of the most fascinating stops on the route to Rome.
